Description

Method for inputting character in mobile terminal}

The present invention relates to a character input method in a mobile terminal.

As in the conventional mobile terminal, a method of inputting alphabetic characters by using a limited number of key buttons is to set a plurality of alphabetic characters in one key button and sequentially input alphabetical characters according to the number of times the key button is pressed.

As described above, a method of repeatedly pressing the same key button has a problem in that a character input speed is slow and typos frequently occur.

For example, to input the letter "HIGH", one key button with GHI is set. First, press the key button twice to enter the letter H. To wait for the predetermined time or enter another button to enter the letter I. You can enter it only by pressing once and then pressing the key button three times again.

Also, if you do not wait for a certain time, the first letter H is changed to I as you press the key button, and in order to enter H again, you must repeatedly press the key button with the GHI set, which causes inconvenience to the user. do.

The present invention relates to a character input method in a mobile terminal to solve the inconvenience caused by inputting a character by repeatedly pressing the same key button as in the prior art to provide the user with convenience when inputting a character.

Inputting letters in a first order allocated to the key button when a key button to which a plurality of letters are assigned is input; And a character assigned to a key button corresponding to the sequence is input as a key button in which the first sequence of characters is input and the next sequence of input characters is input.

According to the character input method of the mobile terminal according to the present invention, it is possible to easily input the alphabetic characters in the desired order among the alphabetic characters assigned to the key button by pressing the key button in which the alphabetical order is set.

In addition, the present invention has the effect that it is possible to easily input the desired alphabetic characters by defining a basic alphabetic character and its derived alphabetic characters, respectively, and by setting a key button for input.

In addition, the present invention can reduce the inconvenience of having to press the same key button repeatedly and thereby a typo generated there is an effect of providing convenience to the user at the time of character input.

In the present invention, if the first sequence of characters is input and after a predetermined time waiting for a key button set the input order is not input, the method further comprises the step of waiting for the character input by shifting the character input cursor.

In addition, the character input method in a mobile terminal according to the present invention comprises the steps of: setting the base type of the character and the character derived from the base type; And when the key button to which the basic type of the character is assigned is input, the allocated basic type character is input, and when the key button for inputting the derived character is input, the input is changed into a character derived from the basic type character. do.

In the present invention, the derived character is characterized in that the stroke is added to the base type character or a modified character that can be associated with the base type character.

In addition, in the present invention, for the convenience of description, an English letter input is described as an example, and the present invention is not limited to the English letter, and may be applied to Korean characters and various other character inputs.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a flowchart illustrating a text input method in a mobile terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 1, when an English character input command is requested, the apparatus waits to receive an English character set in a key button (S11).

Thereafter, it is determined whether the key button is pressed (S12), and the first English letter set to the pressed key button is input (S13).

For example, as shown in FIG. 2A, alphabets A, B, and C are assigned to key 2 and D, E, and F are assigned to key 3, and a plurality of alphabetic letters are sequentially assigned to each key button. Press key to input the first assigned English letter. That is, when the 2nd key button is pressed, the first assigned letter A is input.

Then, if the * button is pressed while the first alphabet is input (S14), the previously input alphabet is erased and the second alphabet letter assigned to the key button is input (S15).

For example, pressing the # 2 key button and pressing the * button while the English letter A is input erases the entered English letter A and sequentially inputs the second assigned letter B.

Here, if the # button is pressed while the first alphabet is input (S16), the previously input alphabet is erased and the third alphabet letter assigned to the key button is input (S17).

For example, pressing the # 2 key button and pressing the # button while the alphabet letter A is input erases the previously entered alphabet letter A and sequentially inputs the third alphabet letter C.

Thereafter, it is determined whether a button for terminating the character input is input (S18), and the above steps are repeatedly performed until the character input is terminated.

Therefore, the present invention sets the alphabet input order to the key button that is not assigned to the alphabet, and as the key button is pressed, the alphabet letter assigned to the key button corresponding to the set order is input so that the key button is repeatedly pressed. You can easily enter the alphabet you want by pressing the key button where the alphabetic order is set.

Referring to FIG. 2 as an example, in order to input an English letter "SKI", as shown in FIG. 2A, the eighth key button is pressed. In this case, the first English letter S assigned to the eighth key button is input to the screen window.

Subsequently, when the 5th key button to which the English letter K is assigned is pressed in order to input the English letter K, the first English letter J assigned to the 5th key button is input to the screen as shown in FIG. 2B.

In this case, when the * button is pressed as shown in FIG. 2C while the alphabet letter J is input, the alphabet letter J displayed on the screen window is erased, and the second letter K is input to the fifth key button.

Thereafter, if the fourth key button to which the English letter I is assigned is pressed in order to input the English letter I, the first English letter G assigned to the fourth key button is input to the screen as shown in FIG. 2D.

In this case, if the # button is pressed as shown in FIG. 2E while the alphabet letter G is input, the alphabet letter G displayed on the screen window is erased, and the letter I allocated to the fourth key button is input.

As described above, the present invention can easily input a desired alphabetic character by pressing a key button in which an alphabetical order of alphabetical characters is input without repeatedly pressing the same key button.

Here, when the key button is pressed for character input, the first assigned alphabet is inputted on the screen, and if the * button or the # button is not pressed after waiting for a predetermined time, the character input cursor is shifted to the side to wait for input of the next character.

In addition, the alphabetical character input order may be input to key buttons that are not limited to the * button and the # button and to which the English letter is not assigned, thereby inputting alphabetical characters in a desired order.

As another example, the alphabetic characters may be divided into basic letters and stroke-added alphabet letters and modified alphabet letters, and strokes are added to key buttons not assigned to the alphabet letters, and the alphabet letters may be easily set by inputting the modified alphabet letters. Explain the example.

First, as shown in FIG. 3, an English letter base type and a stroke derived from the base type are added and a modified English letter is defined.

In more detail, the letter C is defined as G with the stroke added and L as the modified alphabet.

In other words, if you add a stroke to the letter C, G may be associated with L and may be associated with a similarly deformed letter. In this way, the letters A, C, F, I, N, O, P, S, V, Y It assigns to the basic type, defines the English alphabet and the modified English alphabet to which the stroke is added to the basic English alphabet, and sets the key button that can be changed to the English alphabet and the modified English alphabet, the stroke is added.

For example, as shown in FIG. 4, a basic type of an English letter is assigned to a key button, and the # button is set to a key button for changing to an English letter with a stroke added, and the * button is set to a key button for changing to a modified English letter. Define and explain.

First, when the 8th key button is pressed as shown in FIG. 4A to input an English letter "SKI", the English letter S is input to the screen window.

Then, in order to input the English letter K, press the 3 key button as shown in FIG. 4B to input the basic letter F, and press the * button as shown in FIG. C to erase the English letter F and enter the English letter K defined as the modified English letter. Thereafter, as shown in FIG. 4C, the fourth letter is pressed to input the letter I.

In this way, it is possible to easily enter the alphabetic characters by defining the basic alphabetic characters, define the alphabets added to the stroke derived from the basic alphabetic characters and the modified alphabetic characters.

That is, when the key button is pressed for character input, the alphabet assigned to the basic type is inputted on the screen, and after waiting for a predetermined time, the English letter to which a stroke derived from the basic type alphabet is added as a key button such as a # button or a * button is pressed. By inputting the modified English letter, the user can easily enter the English letter.

In addition, the present invention has been described as an example of an English letter, but can be applied to a variety of characters, including Korean characters, and further comprises a case letter change key button, Korean character input switch key button, special character input key button, etc. Therefore, it is possible to provide convenience to the user at the time of text input.

Therefore, the present invention has the effect that it is easy to input the alphabetic characters of the desired order among the alphabetic characters assigned to the key button by pressing the key button set the alphabetical order of the alphabetic characters.

In addition, by defining a basic alphabet letter and its derived alphabet letters, and by setting a key button for input, there is an effect that can easily enter the desired alphabet letters.

In addition, the inconvenience of having to press the same key button repeatedly and thereby resulting in a typo can be reduced, thereby providing convenience to the user when entering text.
